ABSTRACT OF THE DISCLOSURE A method and apparatus are provided herein for displaying moving objects. The method includes the steps of conducting a line scan of an object with a prismatic rotating wheel, the prismatic rotating wheel periphery including a plurality of adjacent, recessed, and oppositely reflecting triplet mirror surfaces. The prismatic wheel is rotated in order that oppositely reflecting triplet mirror surfaces alternately deflect a first signature scan and a second signature scan of the object with a minimum mutual time shift in first and second directions respectively, onto a single detector. The first signature scan is time delayed by an intermediate storage so that it is simultaneously available with the second signature scan. The difference between the signature scans is determined. Finally the remaining uncancelled individual signals in the storage are defined as coordinates of the object, and these coordinates are presented in electronic form as output signals for defining position coordinates of the object. The apparatus includes means for scanning and imaging having a prismatic rotatable wheel for deflecting a first signature scan and a second signature scan of an object with a minimum mutual time shift, the prismatic rotatable wheel periphery having a plurality of adjacent, recessed, and oppositely reflecting triplet mirror surfaces which are adapted to reflect the first and second signature scans in first and second directions respectively; a single detector for receiving the first and second signature scans having a minimum mutual time shift; means for time delaying the first Abstract of the Disclosure (continued page 2) signature scan by an intermediate storage so that it is simultaneously available with the signature scan; means for determining the difference of the signature scans; and means for defining the remaining uncancelled individual signals in the storage as coordinates of the object and means for presenting these coordinates in electronic form as output signals for defining position coordinates of the object.
